Definitions

  • the invention relates to a laminated board made of one or more layers of paper and / or nonwoven fabric, in which hardened resins are embedded, and at least one outer fine layer made of hardened resin, and to a method for producing such a laminated board.
  • This upper fine layer is generally completely sufficient for normal stresses, for example when covering furniture or doors. With extreme stresses alone, such as when used as a worktop in the kitchen area, there is a risk that the smooth surface will show scratches or matt areas more quickly than the less stressed vertical surfaces.
  • DE-A-28 00 762 To increase the abrasion resistance, it is known from DE-A-28 00 762 to apply an ultra-thin layer of aluminum oxide directly onto the decorative paper, which layer is bound by microcrystalline cellulose and then covered with a thin layer of melamine-formaldehyde resin. It is also known from DE-A-29 23 608 to use alumina or silica instead of aluminum oxide.
  • This addition of an abrasion-resistant mineral increases the scratch and abrasion resistance of the laminate, but essentially only in the area of the decorative paper itself and not directly on the surface of the fine layer, which conventionally consists only of the hardened resin.
  • the invention has for its object to provide an abrasion and scratch resistant laminate, in which the entire fine layer itself is designed to be considerably more resistant.
  • the fine layer contains ground and / or cut glass fibers.
  • the proportion of glass fibers in the fine layer can be 1-25, preferably 3-15 and in particular 5-10% by weight.
  • the length of the glass fibers should be 0.1-12 mm, preferably 0.1-1.0 mm, in particular 0.2-0.4 mm.
  • the uncured resin mixed with glass fibers can be applied to at least one of the separating films and pre-cured before the separating films are brought together with the impregnated sheet or sheets.
  • the laminate plate 11 initially has a release paper layer 1 so that the plate slides well on the base during manufacture. This is followed by the actual lower end layer 2 of the polyester resin laminate, followed by a first layer of sodium kraft paper 3 and a further polyester layer 4 as a binder to the next kraft paper layer 5.
  • the subsequent polyester layer 6 establishes the connection to the decorative paper 7.
  • the individual kraft paper layers 3 and 5 and the decorative paper 7 are first dried and soaked with the resin, generally a separate layer of polyester resin being applied to the individual sheets before they are brought together.
  • epoxy resins for the connection and curing instead of the polyester resin.
  • the final fine layer of curable resin, which forms the actual surface of the board, is then applied to the top decorative paper, which can be either monochrome or patterned.
  • this fine layer which generally has a thickness of about 20-200 11m, in particular 50-100 11m, ground and / or cut glass fibers with a length of 0.1-12 mm, preferably 0.1-1, are now according to the invention , 0 mm and in particular 0.2-0.4 mm, the resin of the fine layer evenly mixed so that they completely penetrate the resin.
  • the glass fiber-added, not yet cured fine-layer resin is first applied to the upper release paper 10 according to the drawing or to a release film in the desired thickness and is accordingly pre-cured. After this pre-curing, the release paper 10 with the fine layer 8 and the glass fiber particles 9 contained therein is applied to the decorative paper 7, connected under pressure and then cured under heat. After the finished plate has hardened and cooled, the lower and the upper separating paper 1 and 10 are pulled off and the laminated plate is rolled up or cut to length accordingly.
  • the resin layer 2 can be applied to the lower release paper 1 in the same way as for the upper fine layer 9 as a fine layer mixed with glass fibers, pre-hardened and then pressed onto the paper web.
